Abstract

The disclosed device serves for artificial respiration and has a blower connected to a control. The blower is held by a supporting part, which assumes the task of decoupling and other functions. The blower and the supporting part are arranged in a blower box. Both the control and the blower box are arranged in a housing. The control is connected to at least one indicating device and also to at least one operating element.

First claim

What is claimed is:

1. A device for artificial respiration, wherein the device comprises a blower connected to a control, both the control and the blower being arranged in a housing, and the control being connected to at least one indicating device and at least one operating element, wherein the blower is secured in the housing by a supporting part of a viscoelastic or elastomeric material on which the blower is arranged, and wherein at least one of (i) the supporting part comprises at least two air openings, (ii) the supporting part forms a first seal, which provides a seal with respect to sealing surfaces of two housing parts, and forms a second seal, which provides a seal with respect to different sealing surfaces of the two housing parts and thus pneumatically separates a high-pressure region from an intake region, and (iii) elastic spacing elements which prevent contact between the blower and the housing are provided on one side or both sides of the supporting part.

2. The device of claim 1 , wherein the housing comprises or consists of a front unit, which comprises the indicating device, and two further housing parts, which form a blower box.

3. The device of claim 2 , wherein at least three redirecting features for a flow of respiratory gas are arranged within the blower box.

4. The device of claim 2 , wherein at least one sound-damping element is arranged within the blower box and/or on the supporting part.

5. The device of claim 1 , wherein the viscoelastic or elastomeric material comprises a silicone.

6. The device of claim 1 , wherein the supporting part comprises at least two air openings.

7. The device of claim 1 , wherein the supporting part is secured between two housing parts, the two housing parts respectively comprising associated chamber halves of a high-pressure region and an intake region.

8. The device of claim 1 , wherein the supporting part is arranged in a vertical direction between housing parts.

9. The device of claim 1 , wherein the supporting part forms a first seal, which provides a seal with respect to sealing surfaces of two housing parts, and forms a second seal, which provides a seal with respect to different sealing surfaces of the two housing parts and thus pneumatically separates a high-pressure region from an intake region.

10. The device of claim 1 , wherein the supporting part comprises at least one opening that is surrounded at least in portions thereof by a collar.

11. The device of claim 1 , wherein a line routing for connecting a pressure measurement comprising a line portion of a first diameter and a line portion of a second diameter is present within the device, the second diameter being smaller than the first diameter.

12. The device of claim 1 , wherein elastic spacing elements which prevent contact between the blower and the housing are provided on one side or both sides of the supporting part.

13. A device for artificial respiration, wherein the device comprises a blower connected to a control, both the control and the blower being arranged in a housing, and the control being connected to at least one indicating device and at least one operating element, wherein the blower is secured in the housing by a supporting part of a viscoelastic or elastomeric material on which the blower is arranged, the blower being connected to the supporting part by a coupling element, and wherein at least one of (a) the coupling element surrounds the blower in the form of a frame, (b) the coupling element comprises beads to prevent transmission of structure-borne sound, and (c) elastic spacing elements which prevent contact between the blower and the housing are provided on one side or both sides of the coupling element and/or the supporting part.

14. The device of claim 13 , wherein the supporting part and the coupling element are formed as one part.

15. The device of claim 13 , wherein the coupling element surrounds the blower in the form of a frame.

16. The device of claim 15 , wherein the coupling element is present as a ring.

17. The device of claim 13 , wherein the blower is elastically suspended inside the housing by the supporting part and/or the connecting element.

18. The device of claim 13 , wherein elastic spacing elements which prevent contact between the blower and the housing are provided on one side or both sides of the coupling element and/or the supporting part.

19. The device of claim 13 , wherein the coupling element comprises beads to prevent transmission of structure-borne sound.

20. The device of claim 13 , wherein the supporting part is arranged in a vertical direction between housing parts.
